Two species of Myxobolus Bütschli, 1882 were found in yellow catfish Tachysurus fulvidraco (Richardson). A species of Myxobolus infecting the gills was morphologically identified as Myxobolus voremkhai (Akhmerov, 1960) and it was characterised here with additional morphological and molecular data. The other species of Myxobolus infecting the host's skin did not conform to any known myxosporean species. It is characterised by the presence of round, black or milky white plasmodia with black spots. Myxospores are pyriform in frontal view and lemon-shaped in lateral view, measuring 12.9-16.2 μm (14.6 ± 0.7 μm) in length, 8.1-10.8 μm (9.4 ± 0.5 μm) in width, and 6.1-8.1 μm (7.0 ± 0.4 μm) in thickness. Two ampullaceous polar capsules are slightly unequal in size, larger polar capsule 7.2-9.5 μm (7.9 ± 0.4 μm) long by 3.0-3.9 μm (3.5 ± 0.2 μm) wide, smaller capsule 6.9-8.0 μm (7.4 ± 0.3 μm) long by 2.9-3.9 μm (3.4 ± 0.2 μm) wide. Polar filaments are coiled with seven to nine turns. Histologically, the plasmodia develop in the stratum spongiosum of skin dermis, resulting in epithelial cell shedding and immunological cell infiltration. Given the morphological and molecular differences between this species and other species of Myxobolus, we proposed the name of Myxobolus pseudowulii sp. n. for this parasite from the skin of yellow catfish. Interestingly, some spores of the new species possess Henneguya-like caudal appendages. Phylogenetically, M. pseudowulii sp. n. and M. voremkhai infecting yellow catfish group together in one clade with other parasites of Siluriformes, indicating that parasites clustering according to the fish host order may be an important factor affecting the evolution of species within the Myxobolus clade., Bo Zhang, Yanhua Zhai, Yang Liu, Zemao Gu., and Obsahuje bibliografii
A new fossil genus and species of Sinoalidae, Stictocercopis wuhuaensis gen. et sp. n., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China is described, illustrated and its systematic position discussed, on the basis of four complete well-preserved specimens. The new genus distinctly differs from other sinoalids in having relatively complex wing venation and tegmen spots. The intra-specific variation in venation is also discussed. The new discovery increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds., Yan-Zhe Fu, Di-Ying Huang., and Obsahuje bibliografii
A new progonocimicid bug named Cicadocoris parvus sp. n. is described from the mid-Jurassic Haifanggou Formation at Daohugou, Ningcheng County, Inner Mongolia, northeastern China. It differs from other species by being distinctly smaller, veins dSc, R1 and Rs run parallel to one another and are nearly evenly spaced on left tegmen, widest length of apical half/basal half of left tegmen is 1.1 and that of right tegmen is 1.0. Thus, there are at least three species of Cicadocoris (Progonocimicidae) described from Daohugou. All these species are relatively abundant in the Haifanggou Formation and are remarkable representatives of the early Yanliao biota., Jia-Qian Jiang, Di-Ying Huang., and Obsahuje bibliografii
Babesia caballi (Nuttal, 1910) is one of the causative agents of equine piroplasmosis which causes economic losses to horse industry in China. There is an urgent need for rapid detection method for B. caballi infection in Xinjiang Province, China. To prepare monoclonal antibodies (mAbs) against Bc48 gene of B. caballi (Xinjiang local strains) and establish colloidal gold-immunochromatographic (ICT) assay for diagnosis of the disease, recombinant Bc48 was expressed and purified from Escherichia coli. With purified Bc48 as immunogen in mice, three hybridoma cells named 11F4, 1H2 and 7F4 secreting mAbs against Bc48 of B. caballi were obtained, which showed strong reaction with recombinant Bc48 and Bc48 gene transfected cells. Furthermore, colloidal gold labelled ICT assay based on purified Bc48 recombinant antigen and its mAb was developed. The ICT assay showed high sensitivity and specificity and no cross-reaction with Theileria equi (Laveran, 1901). Total of 56 horse serum samples collected from Xinjiang were tested by ICT and compared with the detection by commercial ELISA kit. The results showed that 32 out of 56 serum samples were positive by ICT and 33 were positive by ELISA. ICT assay had high coincidence (98%) to the reference ELISA kit. mAbs and ICT developed in this study could be provided as an efficient diagnosis tool for infection with B. caballi in horse in Xinjiang area., Panju Wang, Jingjing Song, Ruiqi Song, Mengyuan Zhang, Lijiang Wu, Fangxin Li, Yan Yan, Jiyong Zhou, Bayin Chahan, Min Liao., and Obsahuje bibliografii
Seven new species of chewing lice in the genus Resartor Gustafsson et Bush, 2017 are described and illustrated. They are: Resartor albofulvus sp. n. ex Heterophasia desgodinsi desgodinsi (Oustalet); Resartor apimimus sp. n. ex Heterophasia picaoides wrayi (Ogilvie-Grant); Resartor aterrimus sp. n. ex Minla ignotincta mariae La Touche; Resartor extraneus sp. n. ex Lioparus chrysotis swinhoii (Verreaux); Resartor guangxiensis sp. n. ex Trochalopteron milnei sinianum Stresemann; Resartor longisuturalis sp. n. ex Actinodura cyanouroptera wingatei (Ogilvie-Grant); Resartor seminudus sp. n. ex Leiothrix argentauris tahanensis (Yen). All species differ in the shape of the head, shape of the male genitalia and abdominal chaetotaxy. A checklist and a key to the species of Resartor are provided., Daniel Roland Gustafsson, Xingzhi Chu, Sarah Elizabeth Bush, Fasheng Zou., and Obsahuje bibliografii
